MELEE08 is a smallish but good Deathmatch WAD that's great for any number
of players. It features weapon mixes controllable via the difficulty levels,
and is generally pretty good. No glitches or badly mapped textures of any
kind. I've put some time into making sure that everything is lined up the way
I want it to be. There's one wall that you might "catch" on, but I can't do
anything about that, and you might not notice anyway.
